Tomatoes are especially good choices, because their flavor improves greatly when they're allowed to mature on the plant. Heirloom tomatoes such as the "Super Sioux" variety (Solanum lycopersicum "Super Sioux") can be especially flavorful. The University of Nebraska developed and released a tomato plant called Sioux in 1944, the progenitor of the cultivar "Super Sioux," which was developed later by selecting plants that produced extra-large fruit. The plant grows as a vine, which is the typical growth habit of tomatoes. This variety is classified as an indeterminate plant because the vine continues getting taller as the season progresses, unlike determinate types that reach a particular height and then stop growing. Super Sioux" tomatoes are bright red in color, usually between 2 and 4 inches in diameter and weigh 4 to 6 ounces each. The fruits have smooth skin and are thick-walled, with relatively small seed cavities. Their flavor is typical of an old-fashioned tomato, with sweetness mixed with an acidic "bite." They are versatile fruits and useful for fresh slicing, canning or making tomato sauce. You can start "Super Sioux" tomato plants indoors 6 to 8 weeks before your last frost date, sowing 1 or 2 seeds in each peat pot or planting cell. Use sterile potting soil or a soil-less mix to minimize damping off, a fungal problem in young seedlings. In warm areas, you can direct-sow seeds once temperatures remain above 60 degrees Fahrenheit, choosing a site that receives full sun for most of the day.
